Protein attributes
| Sequence length | 745 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Constitutively active serine/threonine-protein kinase that exhibits growth-factor-independent kinase activity and that may participate in p53/TP53-dependent cell growth arrest signaling and play an inhibitory role during embryogenesis. Ref.6 Ref.7 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium By similarity. |
| Enzyme regulation | Constitutively activated by phosphorylation at Ser-232, Ser-372, and Ser-389 in serum-starved cells. Does not require growth factor stimulation for significant kinase activity. Ref.7 |
| Subunit structure | Forms a complex with MAPK3/ERK1 but not with MAPK9 or MAPK14 in serum-starved cells. |
| Subcellular location | Cytoplasm › cytosol. Nucleus. Note: Predominantly cytosolic. Ref.7 |
| Post-translational modification | Phosphorylated at Ser-232, Ser-372, and Ser-389 in serum-starved cells. Ref.7 |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 2 protein kinase domains. |
